FX Sport 4 is a carbon fiber fitness bike for riders who want the speed of a lightweight road bike with the comfort and control of a flat handlebar. An IsoSpeed decoupler smooths out rough roads and the 1×11 drivetrain simplifies shifting without sacrificing gear range, making this high-performance bike perfect for everything from solo workouts to speedy group rides.
Its right for you if…
Youre ready to log big miles, and you prefer the feel of a flat handlebar to the drop bars that come stock on most road bikes. You prioritize comfort and performance equally, and want the simplicity a 1x drivetrain provides.
The tech you get
A lightweight OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a Shimano GRX 1×11 drivetrain with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheelset, and ergonomic grips. Plus, its easy to accessorize with fenders, lights, and more!
The final word
Fast, capable, comfortable. This bike has a road-smoothing carbon frame and quality parts that will hold up over serious miles, but what really sets this model apart is the simpler shifting experience the 1×11 drivetrain provides.
